摘　　要：调查和有关资料显示,我国平原城市洪涝频发。城市控制圈是平原城市分片有效防治洪涝的主要途径和形式。无锡市建设的城市控制圈取得了防治洪涝和改善河道水环境的良好效果,其模式可供全国类似平原城市借鉴。建设控制圈的原则包括:编制适度超前的城市洪涝防治规划和建立相应的体制机制;设置符合实际的城市洪涝防治高标准;设计适当规模的控制圈,分区消除洪涝;加强城市洪涝防治技术集成;控制圈与海绵城市同步实施,建设大海绵城市。控制圈有效防治洪涝的关键是有超前意识,挡洪、蓄滞和排涝的高标准,河道和雨水管道统一的排涝标准。建设控制圈的总体思路为:规模适当,应建尽建,分区分片防治洪涝;上游和河道具有足够的蓄滞和行洪能力;合理选择控制圈外的排水路径;控制圈内有足够的排涝能力;制定科学适用的超标准洪涝防治预案。It is shown in the investment and related data that floods take place frequently in plain cities of our country. City control circle is the main route and form to effectively prevent and control floods. The city control circle established in Wuxi is working well in prevent and control flood in plain city and improve water environment, and provides a reference to similar regions in our country. The principles of establishing city control circle include： to develop appropriately advanced city flood prevention and establish control plans and corresponding system and mechanism, to set practically high standards of city flood prevention and control, to establish proper scale of control circle to eliminate flood in partition, to reinforce technology integration of city flood prevention and establish control, to simultaneously construct the control circle and sponge city and to build great sponge city. The keys of control circle to effectively prevent and control floods are superior consciousness, high standard in blocking flood, storing flood and drainage, and unified drainage criterion of stream channel and rainwater pipeline. The general thoughts of establishing city control circle are ： scale should be appropriate, construction is to be the greatest extent, and flood prevention and control should be in partition and sharding; upstream and stream channel have the sufficient capacity of storing and drainage; drainage paths out of control circle are selected properly; control circle has sufficient capacity of drainage ; scientific and applicative flood prevention and control plans, which are above the standard, are to be set up.
